[0002] In the prior art, there are the following problems in the process of arranging optical fibers on flexible boards: 1) The arrangement accuracy is low, especially in long distances, such as 0.5-1m. Distortion and deviation caused by excessive angular error after vertical steering arrangement; 2) Uneven optical fiber arrangement pressure. After the optical fiber is arranged on the viscous flexible board, appropriate pressure needs to be applied to ensure reliable adhesion. The existing technology often There is no pressure adjustment mechanism, and the arrangement pressure cannot be adjusted in real time according to the arrangement working conditions. Under extreme working conditions, the lack of pressure may cause the fiber bonding to fail or the fiber may be broken due to excessive pressure; 3) During the process of fiber transportation and arrangement, Due to the inconsistency between the fiber pay-off speed and the arrangement speed, it is very easy to cause damage or breakage of the optical fiber; 4) The pressure roller used after the optical fiber is bonded often causes the adjacent optical fiber to be crushed twice or more due to structural problems, resulting in Damaged or crushed optical fiber

Compared with the present invention, this technology has further technical problems that cannot be solved: 1) It does not involve pressure detection and adjustment mechanisms, that is, it cannot detect the current fiber distribution pressure, nor can it adjust the fiber distribution pressure in real time on this basis; 2) ) does not involve the tension detection mechanism, and the fiber unwinding process is a passive process, which cannot realize the matching adjustment of the fiber unwinding speed and the fiber cloth movement speed; 3) does not involve the arranged optical fiber length detection device, and cannot realize precise arrangement
